Hint 1. How to approach the problem
First, determine the distance at which the original path of the light leaves
medium 2 in the direction along the layer of medium 2. Next, use Snel's law to
determine how the direction of the ray changes in the medium 2 because of
the refraction. Then determine where the refracted ray exits medium 2. After
that determine the distance between the exit points of the original path and the
refracted ray, then determine the perpendicular distance between the original
path and the ray leaving medium 2.
